Archiving mail on the google server

Hello. I will be installing Zimbra desktop for a 32-bit Linux platform later. I used Zimbra a while ago and, if memory serves me, when I delete an e-mail from Zimbra, it deletes it on the gmail server rather than archiving it, as Evolution and other clients do. Can I somehow tell Zimbra to archive an e-mail on the gmail server rather than delete it? I couldn't find a keystroke to do this. In Thunderbird, for example, if you press "delete" it deletes the e-mail from the Thunderbird client AND the gmail server. But pressing "A" instead deletes it from Thunderbird but archives the mail on the gmail server. This is the kind of behavior I would love to get Zimbra to do.
